E1 To Ethernet Converter

framed E1-FE Converter

Overview
This interface converter is based on FPGAproviding one framed E1 interface and one Ethernet interface to achieve 10/100base-T Ethernet data transmission on the E1 channel. It is a high performance self-learning Ethernet bridge. This device is the extension device of Ethernet using network (PDH/SDH/Microwave) that provide E1 channel to achieve local and remote Ethernet interconnecting with serial interfaces at a lower cost. The device has inter-set loop test function to facilitate the project launching and daily maintenance.
Features
◆ based on self -copyright  IC ;
◆ Can realize monitor and control of remote equipment OAM management data did not  take up user’s timeslot and save E1 bandwidth;
◆ E1 supports any timeslot set the rate is 64K-2048K;
◆ The local device can forced the remote device rate follow it;
◆ Have the function of E1 interface loop back check avoid the converter crashed because of interface loop return;
◆ Have indicator  when the device is power-off or E1 line is broken or lose signal;
◆ Can set the E1 line that not to send the link signal to Ethernet interface while E1 line is broken;
◆ The Ethernet interface supports jumbo frames (2036 Bytes);
◆ Inter-set dynamic Ethernet MAC address (4096) with local data frame filtering ;
◆ Ethernet interface supports10M/100M half/full duplex auto- Negotination and AUTO-MDIX (crossed line and straightly connected line self-adaptable );
◆ Have Ethernet monitor self-reset function the equipment will not dead;
◆ Can achieve the remote device setting any 5 mode of Ethernet and can closed the AUTO-MDIX function; 
◆ Provide 2 clock types: E1 master clock and E1 line clock;
◆ Have three Loop Back Mode: E1 interface Loop Back (ANA)、Ethernet interface Loop Back(DIG)、Command the remote Ethernet interface Loop Back(REM) ;
◆ Provide 2 impedances: 75 Ohm unbalance and 120 Ohm balance;
◆ Support SNMP Network Management;
◆ Can realize monitor of remote equipment temperature and voltage from local equipment;  
◆ Can form the structure: Ethernet E1 Bridge(A)---E1 Optical Fiber Modem(B)---Ethernet Optical Fiber Modem (C) ;
◆ Can form the structure: Ethernet E1 Bridge(A)---Optical Ethernet Modem(B)---Ethernet Optical Fiber Transceiver (C) can manage (B) and (C) at (A).
